objective(s): previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. the aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. materials and methods: four weeks after surgeries (left anterior descending (lad) artery occlusion), chr...

The temperature dependence of surface-induced atomic layering in liquid gallium has been investigated with x-ray reflectivity. The prominent layering peak at qz52.4 Å 21 decreases dramatically upon heating from 22 to 170 °C, but its width stays, unexpectedly, unchanged. The decrease is traced to the temperature dependence of capillary-wave induced surface roughness. The constant width indicates...

The influence of additional thermal and thermomechanical treatment PA6/MMT nanocomposites obtained from the formic acid solution on their heat resistance technological properties was investigated. Thermal analysis established that heating nanocomposite to a temperature 250 ºС treating it capillary plastometer IIRT at 230 increases degree crystallinity samples. It is shown additionally treated a...

Sodium dodecyl sulfate capillary gel electrophoresis (reduced and nonreduced) is often used as a purity release assay for monitoring clips in monoclonal antibodies (mAbs). Our criteria for the development of acid hydrolysis of Trastuzumab for injection (Cipla 302) included quantification of clips by both reduced and nonreduced capillary gel electrophoresis thereby comparing its similarity with ...

A fabric can be considered as a porous medium, its porosity size and temperature will greatly affect air/moisture permeability thermal comfort. This paper studies the effect of on capillary rise experimentally, experimental data reveal that higher results in rise, result, better is predicted. elucidates also favorable for effective washing.

Capillary suspensions, solid-liquid-liquid systems, are conventionally formulated by dispersing the particles in bulk phase and then adding a small amount of secondary liquid (<5 vol%), leading to increased yield stress. Previous work has shown that partially miscible liquids form capillary bridges between upon temperature induced separation. In this work, we show suspensions can be formed mixi...

A new method for rapidly constructing isobaric temperature-composition-mesomorph (T-C) diagrams is described. The method involves establishing a lyotrope concentration gradient in a liquid crystal lengthwise in an x-ray capillary tube. At a fixed temperature such a sample corresponds to an isotherm in the corresponding isobaric T-C diagram. The concentration gradient is conveniently established...

We derive a sophisticated mathematical model for coupled heat and mass transport in the tumour microenvironment and we apply it to study nanoparticle delivery and hyperthermic treatment of cancer. The model has the unique ability of combining the following features: (i) realistic vasculature; (ii) coupled capillary and interstitial flow; (iii) coupled capillary and interstitial mass transfer ap...

We demonstrate measurement and control of single-asperity friction by using cantilever probes featuring an in situ solid-state heater. The heater temperature was varied between 25 and 650 °C (tip temperatures from 25 ± 2 to 120 ± 20 °C). Heating caused friction to increase by a factor of 4 in air at ∼ 30% relative humidity, but in dry nitrogen friction decreased by ∼ 40%. Higher velocity reduce...

PURPOSE The aim of the study was the development of a simple and rapid analytical procedure for the determination of the most frequently used antihistamine derivatives. METHODS A capillary zone electrophoretic method was developed for the simultaneous separation of loratadine, desloratadine and cetirizine. Efforts were focused primarly on the optimisation of the experimental parameters: buffe...
